Grinders

Coffee Grinder Repairs in Cape Town

A grinder does more for shot quality than most machines get credit for. When burrs wear or alignment drifts, no amount of adjusting on the espresso machine will bring the shot back.

ExoCoffee repairs and recalibrates domestic and commercial espresso grinders across Cape Town.

Who this is for

Cafés

On-demand grinders doing hundreds of doses a day where consistency decides the shot.

Roasters and retailers

Shop grinders that must produce repeatable grind across brew methods.

Home baristas

Domestic grinders that have become noisy, inconsistent or impossible to dial in.

Grinder problems we fix

Worn burrs

Longer grind times, more fines, and shots that channel no matter how you tamp.

Inconsistent grinding

Dose or particle size varying between shots, often from burr wear or misalignment.

Motor issues

Motor bogging down under load, overheating, cutting out or failing to start.

Jammed grinders

A stone or foreign object in the burrs, or compacted coffee locking the chamber.

Adjustment and calibration problems

An adjustment collar that slips, sticks or no longer corresponds to grind size.

Electronic faults

Timer and dosing electronics, switches and control boards behaving erratically.

Abnormal noise

Bearing whine, rattling or metal-on-metal contact between the burrs.

What we check

  • Burr sharpness, edge condition and estimated remaining life
  • Burr carrier alignment and runout
  • Motor current draw, bearings and thermal protection
  • Adjustment mechanism threads, detents and collar security
  • Dosing timer accuracy and switch or sensor operation
  • Chute and chamber build-up of stale grounds and coffee oils

How grinder work is done

  1. 1. Grind assessment

    We look at the actual grind and dose behaviour, not just the symptom described.

  2. 2. Strip and clean

    Burr chamber, chute and adjustment mechanism cleaned of compacted grounds and oils.

  3. 3. Burrs and bearings

    Worn burrs replaced with correct-spec sets, bearings and seals attended to as needed.

  4. 4. Calibration

    Alignment set, then grind dialled back in against a live extraction.

Grinder types

  • On-demand espresso grinders
  • Doser grinders
  • High-volume commercial grinders
  • Domestic burr grinders
  • Grinders built into bean-to-cup machines

Questions

Grind time per dose creeping up, more fines and dust, and shots that channel or run unpredictably are the usual signs. Burr life depends on volume and burr material.

Yes. Alignment is checked and corrected during a service; poor alignment produces uneven particle size even with new burrs.

Stop using it. Metal contact usually means the burrs are touching or a bearing has failed, and continuing will damage the carriers.
